   An organization wants to ensure that every validated build of its network automation code can be deployed to a production-like staging environment with minimal manual effort, but a human must still approve the final production release. Which approach best meets this requirement?

   • AContinuous integration only, where code is merged and tested but never deployed automatically.
   • BContinuous delivery, where the pipeline automatically deploys to staging after passing tests and requires manual approval for production.
   • CManual deployment scripts that are run by an operator whenever a release is needed.
   • DContinuous deployment, where every change that passes tests is automatically released to production.

   In a traditional organization, developers write code and 'throw it over the wall' to operations, who are responsible for deploying and maintaining it. This leads to frequent misunderstandings and delays. The organization wants to adopt DevOps to improve collaboration. What is the most important cultural change to implement?

   • AImplement a ticketing system for all deployment requests
   • BIncrease the number of status meetings between development and operations
   • CMove all operations tasks to the development team
   • DCreate cross-functional teams where developers and operations share responsibility for the entire lifecycle

   A network team must provision identical lab environments for multiple developers. Currently, they manually configure VLANs, interfaces, and routing on each switch, which leads to inconsistencies. They want to store the network configuration in a Git repository and use a tool to apply it automatically to any switch. Which practice should they adopt?

   • AContinuous integration
   • BInfrastructure as code
   • CConfiguration management
   • DContinuous deployment

   What is the main difference between continuous deployment and continuous delivery?

   • AContinuous deployment requires manual approval before production, while continuous delivery is fully automated
   • BContinuous deployment automatically releases every change to production, while continuous delivery requires a manual release decision
   • CContinuous deployment is used only for infrastructure changes, while continuous delivery is for application code
   • DContinuous deployment is a subset of continuous integration, while continuous delivery is a separate practice

   A DevOps team wants to improve their delivery process but is unsure which changes have the most impact. They have access to deployment frequency, lead time, change failure rate, and mean time to recovery data. Which practice should they use to drive improvement?

   • AUse the metrics to identify bottlenecks and run experiments to test improvements, then review results in retrospectives.
   • BShare the metrics only with management to justify budget requests.
   • CIgnore the metrics and rely on intuition from senior engineers.
   • DFocus only on increasing deployment frequency, regardless of other metrics.
